When it is necessary to disassemble the second plug assembly 22 and the second socket portion 13, firstly, reversely pull the second handle portion 223F of the second locking member 223 in the longitudinal direction Y, the second holding portion 223D presses the second elastic portion 223C to make the other end of the second elastic portion 223C move toward the second base portion 223A until the second holding portion 223D is disengaged from the second fixing groove 221D, and at this time the second extending portion 223B is positioned at an outer side of the second connecting member 222 in the longitudinal direction Y; then the other end of the second connecting member 222 is pressed downwardly to relieve the latching between the one end of the second connecting member 222 and the second connecting portion 132; later the second plug assembly 22 is pulled out from the second socket portion 13.

In order to facilitate the cooperation between the second latching portion 223D and the second fixing groove 221D, an outer surface of the second latching portion 223D may be a smooth curved surface.

Referring to FIG. 7, the main body portion 11 is provided with an avoiding groove 11A facing the second connecting portion 132 of the second receptacle portion 13.

Alternatively, the first conductive terminal 215 is provided with an inserting pin, the second conductive terminal 224 is provided with an inserting hole.

Referring to FIG. 3 to FIG. 5, the first plug assembly 21 may further comprise a first wire harness body 216 connected (e.g., clamped) to one end of the first conductive terminal 215 away from the second conductive terminal 224. The second plug assembly 22 may further comprise a second wire harness body 225 connected (e.g., clamped) to one end of the second conductive terminal 224 away from the first conductive terminal 215. The first wire harness body 216 is used for electrically connecting the power supplying device outside the box, the second wire harness body 225 is used for electrically connecting the heating film inside the box.

Referring to FIG. 3 to FIG. 5, the first plug assembly 21 may further comprise: a first sealing ring 217 provided between the first wire harness body 216 and the first shell 211; and a fixing cover 218 fixed to the first shell 211 by the manner of latching. When mounting the fixing cover 218, the fixing cover 218 simultaneously presses the end surface and the outer circumferential surface of the first sealing ring 217, therefore a good sealing interface can be formed between the first wire harness body 216 and the first shell 211.

Referring to FIG. 3 to FIG. 5, the second plug assembly 22 may further comprise a second sealing ring 226 provided between the second conductive terminal 224 and the second shell 221 to seal the second conductive terminal 224 and the second shell 221.

Referring to FIG. 4, the battery product may further comprise: a first sealing member A sealing the first plug assembly 21 and the first receptacle portion 12; and a second sealing member B sealing the second plug assembly 22 and the second receptacle portion 13.
